Array substrate, manufacturing method, and display device
Embodiments of the present disclosure provide an array substrate, a manufacturing method, and a display device. The array substrate comprises: a pixel define layer located on a base substrate, the pixel define layer having a hollow for defining a sub-pixel light emitting area, and a light emitting functional layer located in the hollow, wherein, the pixel define layer has protrusion structures on one or more sides facing the hollow.
1. An array substrate, comprising:
a pixel define layer located on a base substrate, the pixel define layer having a hollow for defining a sub-pixel light emitting area, and
a light emitting functional layer located within the hollow,
the pixel define layer includes stacked a first pixel define layer and a second pixel define layer, the second pixel define layer being located on a side of the first pixel define layer facing away from the base substrate;
the first pixel define layer has lyophilicity, a first surface of the second pixel define layer that faces away from the base substrate has lyophobicity, and a second surface of the second pixel define layer that extends from the first surface toward the base substrate has lyophilicity;
the hollow includes a first hollow located in the first pixel define layer and a second hollow located in the second pixel define layer, and the second hollow exposes a portion of the first pixel define layer that is around an edge of the first hollow;
the first hollow and the second hollow both have two opposite long sides and two opposite short sides;
each of two sides of the second pixel define layer facing the two opposite long sides of the second hollow has more than two protrusion structures; and
two sides of the second pixel define layer facing the two opposite short sides of the second hollow are substantial flat.
2. The array substrate according to claim 1 , wherein
the protrusion structures are disposed opposite to each other.
3. The array substrate according to claim 1 , wherein
the one or more sides of the pixel define layer having the protrusion structure are polygonal surfaces or arc-shaped surfaces.
4. The array substrate according to claim 1 , wherein
the light emitting functional layer is formed by inkjet printing.
